Bode & Nyquist vs Compare Text

This application allows you to plot the Bode and Nyquist diagrams of a transfer function and visualize its impulse response, providing tools to analyze both frequency-domain behavior and time-domain dynamics. The transfer function is entered via a simple numeric keypad and has been specially adapted to make immediately available all the keys you need. Open Loop Transfer function or the Closed Loop Transfer can be entered separately. The app automatically evaluate system stability. The number of unstable closed-loop poles, the number of unstable open-loop poles and the number of clock-wise encirclements of point -1+j0 are shown together with the Nyquist Plot. Gain and Phase margin are shown together with the Bode Plot. For each graph the following gestures are supported: * Drag: To move the chart in the desired position; * Pinch: To enlarge or shrinks the graph; * Double Tap to restore the position and zoom level of the graph to their original values​​. Through a dedicated function you can set the maximum frequency of the Nyquist diagram and the frequency range for the Bode diagrams of the module and phase. There is also a complete online help. BEFORE LEAVING AN ANONYMOUS NEGATIVE FEEDBACK AND THROW AWAY YOUR MONEY: 1) READ THE MANUAL AGAIN; 2) CHECK AGAIN THE SYNTAX OF THE ENTERED FUNCTION; 3) CONTACT ME, AND I WILL DO MY VERY BEST TO HELP YOU. A promo code for my Circuit Lab app will be send to users who will be able to report a recognized bug of this application.

Sometimes you just need to know what changed. Maybe you tweaked a paragraph and want to see exactly what's different. Maybe someone sent you a "slightly updated" contract. Maybe you're staring at two config files that are supposed to be identical but clearly aren't. Compare Text does one thing well: it puts two pieces of text next to each other and shows you what's different. Deleted bits turn red on the left, new bits turn green on the right, and a small counter tells you how much changed at a glance. It works on anything you can paste or open — plain text, code, JSON, emails, contracts, notes. A few things that make it nicer to use: • Paste straight from your clipboard, or open a text file • Ignore case or extra spaces when those don't matter to you • Wrap long lines so nothing runs off the edge • Line numbers, so it's easy to say "look at line 12" • Not sure where to start? Tap Sample to see it in action And it stays with you. No account, no ads, and your text never leaves the phone — the comparison runs right on your device, even offline. It's the same Compare Text tool people use on the web, just sized to fit in your pocket.
